Action potential refers to an event in which the membrane potential of a cell first increases before decreasing. It is a signature characteristic of several human cells, which include muscles, neurons, and cell types that are endocrine. Plant cells can also produce them. Neurons play an important function in cell-to-cell communication. In beta cells of pancreas action potentials are linked with releases of insulin. Plasma membrane has special type of ion channels with voltage-gated voltages for producing action potential. These channels remain closed as long as the potential of the membrane is within what is the limit of cells, however If the membrane's current potential rises then the channels are activated. The channels that are active allow an inward flow of sodium ions that boost your membrane's potential. The fast inward flow of sodium ions results in changing the membrane's polarity and they become inactive. The potassium channels after that are activated and inward flows of potassium ions . This causes the membrane is returned to its original state. A transient positive shift known as refractory interval prevents further forward motion of an action potential. In the cells of animals, generally two types of these potentials are acknowledged, one is generated from voltage-gated potassium channels and the other which is produced due to calcium channels that are voltage-gated.

The majority of cells have an electrical voltage gap between their interior and exterior environment. The cell's voltage is measured in millivolts (mV). The voltage of a typical animal cell is around -70 mV. In the majority cells, low voltage variations are thought for their existence, but in some cells this may be a common characteristic. Certain cells can also exhibit fluctuations in voltage as the voltage drops and increases. The duration of these potentials vary over a wide range. In brain cells the down and up cycle of action potential are completed in less that a thousandth of a second while in other types of cells the cycles may take several seconds. The electrical property of an animal cell is dependent upon the membrane structure. Cell membranes are composed of two layers of lipids and proteins. The lipid layer acts as an insulation.

All animal cells are electrically polarized , as they sustain a voltage difference called membrane potential. In case of the neurons, dendrites and cell body have different electrical properties. The most exuberant part of a neuron is the axon hillock. However, axons and cells body can also be stimulated. The axon hillock's threshold potential for resting is -70mV and the threshold is 55 mV. Synaptic inputs into the neuron cause depolarization, causing the membrane potential to rise or decrease. The action potential is generated when enough depolarization builds up until the membrane potential reaches a threshold value.

Action potential is the result of the work of voltage-gated Ion channels which are located within the plasma membranes of cells. The voltage-gated channel is actually a group of proteins which remain in the plasma membrane. This produces motion potential because it can trigger an positive feedback loop. Membrane potential is accountable for maintaining the state of the these channels. The action potential is created by the positive feedback cycle that continues at its fullest. The time and the intensity are dependent on the bio-physical properties of the ion channel voltage-gated. Ion channels of various types are recognized that create positive feedback cycles , which eventually produce these potentials. Voltage-gated sodium channels are involved in generation of faster potentials , similar to those that result from nerve impulse. These are the ones that are slower, similar to those found in the muscles are controlled by the calcium Ion channels.The most thoroughly studied voltage-gated Ion channels are the sodium ion channels which are involved in the faster conduction of nerve impulses.
